Error while debugging

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Execute client32.exe remote debugger on a Windows XP system

What is the expected output? What do you see instead?
I expect the remote debugger to function properly.  However, I see the error 
message 'Error: Breakpoint handler failed' multiple times.  I also occasionally 
see 'Error: Malformed packet passed to function (Command cmd_setbps)'

What version of the product are you using? On what operating system?
4.0.6

Please provide any additional information below.

Hi Adam,

we would like to reproduce the steps which resulted in the specified error. Are 
you able to share the executable with us that results in the error described 
and the exact steps that you took for the error to appear? Also it would be 
interesting to know if the source IDB has been completely cleaned before the 
executable was loaded into the BinNavi database. We are looking forward to your 
answer.

Best Regards, 

Tim Kornau

Sadly I am not able to provide the binary, because it is in development right 
now.  I did not explicitly clean up the IDB before I loaded it, so I just now 
reloaded the IDB after I closed/garbage collected it.  The same issue persists.

Hi Adam,

Ok if you can not provide the IDB please specify what kind of operation you did 
perform using the debugger. Did you use the trace mode? Did you use a normal 
break point? Did you do anything else of importance? What is the user you 
started the debugger with? Did you try to debug any for of malware which has 
any protection mechanisms in place?
To clarify on cleaning up the IDB, I did not mean you to collect the garbage in 
the IDB but to make sure that there are no significantly large "red" spots in 
the disassembly where IDA did not define a function. 

Best Regards,

Tim Kornau

- I was attempting to trace through a program
- I set a normal breakpoint (CTRL + right-click)
- I am remote debugging; the remote debugging instance is running as 
administrator, the local BinNavi instance is running as a normal user
- No protection is present on the binary (not malware or anything like that)
- There are not any 'bad' sections in the IDB; IDA was able to dissasemble the 
program fine.

Hi Adam,

could you please send your licence key to zynamics-support@google.com. We will 
check if you are still in the upgrade period for our new release and send you a 
new version. Hopefully this will then resolve the problem. If the problem still 
persists we will need to find a file which has similar behavior, and that you 
can share with us.

Best Regards,

Tim Kornau
